Socialist feminist, journalist and activist in the United States. Waters became involved in Trotskyist politics at a young age, and joined the Socialist Workers Party (SWP) in the 1960s. She became the editor of their youth paper, Young Socialist, and the national secretary of the Young Socialist Alliance. In the early 1980s, Waters, along with Jack Barnes and others in the SWP leadership, began to reject the label of "Trotskyism" and the theory of Permanent Revolution, in favour of building links with the Cuban Communist Party and Sandinista National Liberation Front. Today, Waters is the President of the Pathfinder Press and the editor of New International magazine. She has written a number of books on political topics.
